The Modal component is a simple way to present content above an enclosing view.

Note: If you need more control over how to present modals over the rest of your app, then consider using a top-level Navigator.

import React, { Component } from 'react'; import { Modal, Text, TouchableHighlight, View } from 'react-native';

class ModalExample extends Component {

state = { modalVisible: false, }

setModalVisible(visible) { this.setState({modalVisible: visible}); }

render() { return ( <View style={{marginTop: 22}}> <Modal animationType={"slide"} transparent={false} visible={this.state.modalVisible} onRequestClose={() => {alert("Modal has been closed.")}} > <View style={{marginTop: 22}}> <View> <Text>Hello World!</Text>

Props #

animated?: bool #

Deprecated

Use the animationType prop instead.

animationType?: enum('none', 'slide', 'fade') #

The animationType prop controls how the modal animates.

slide slides in from the bottom
fade fades into view
none appears without an animation

Default is set to none.

onShow?: function #

The onShow prop allows passing a function that will be called once the modal has been shown.

transparent?: bool #

The transparent prop determines whether your modal will fill the entire view. Setting this to true will render the modal over a transparent background.

visible?: bool #

The visible prop determines whether your modal is visible.

androidhardwareAccelerated?: bool #

The hardwareAccelerated prop controls whether to force hardware acceleration for the underlying window.

androidonRequestClose?: Platform.OS === 'android' ? PropTypes.func.isRequired : PropTypes.func #

The onRequestClose callback is called when the user taps the hardware back button.

iosonOrientationChange?: function #

The onOrientationChange callback is called when the orientation changes while the modal is being displayed. The orientation provided is only 'portrait' or 'landscape'. This callback is also called on initial render, regardless of the current orientation.

iossupportedOrientations?: [enum('portrait', 'portrait-upside-down', 'landscape', 'landscape-left', 'landscape-right')] #

The supportedOrientations prop allows the modal to be rotated to any of the specified orientations. On iOS, the modal is still restricted by what's specified in your app's Info.plist's UISupportedInterfaceOrientations field.
